France
–
France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans 643,801 square kilometres and had a population of almost 67 million people as of January 2017. It is a unitary republic with the capital in Paris. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse, during the Iron Age, what is now metropolitan France was inhabited by the Gauls, a Celtic people. The area was annexed in 51 BC by Rome, which held Gaul until 486, France emerged as a major European power in the Late Middle Ages, with its victory in the Hundred Years War strengthening state-building and political centralisation. During the Renaissance, French culture flourished and a colonial empire was established. The 16th century was dominated by civil wars between Catholics and Protestants. France became Europes dominant cultural, political, and military power under Louis XIV, in the 19th century Napoleon took power and established the First French Empire, whose subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a succession of governments culminating with the establishment of the French Third Republic in 1870. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War, the Fifth Republic, led by Charles de Gaulle, was formed in 1958 and remains to this day. Algeria and nearly all the colonies became independent in the 1960s with minimal controversy and typically retained close economic. France has long been a centre of art, science. It hosts Europes fourth-largest number of cultural UNESCO World Heritage Sites and receives around 83 million foreign tourists annually, France is a developed country with the worlds sixth-largest economy by nominal GDP and ninth-largest by purchasing power parity. In terms of household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, France remains a great power in the world, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a member state of the European Union and the Eurozone. It is also a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, originally applied to the whole Frankish Empire, the name France comes from the Latin Francia, or country of the Franks

Picardy
–
Picardy is a historical territory and a former administrative region of France. Since 1 January 2016, it is now part of the new region of Hauts-de-France and it is located in the northern part of France. The historical province of Picardy stretched from north of Noyon to Calais, via the whole of the Somme department, the province of Artois separated Picardy from French Flanders. From the 5th century the area was part of the Frankish Empire, and in the period it encompassed the six countships of Boulogne, Montreuil, Ponthieu, Amiénois, Vermandois. According to the 843 Treaty of Verdun the region part of West Francia. The name Picardy was not used until the 12th or 13th century, during this time, the name applied to all lands where the Picard language was spoken, which included all the territories from Paris to the Netherlands. In the Latin Quarter of Paris, people identified a Picard Nation of students at Sorbonne University, during the Hundred Years War, Picardy was the centre of the Jacquerie peasant revolt in 1358. From 1419 onwards, the Picardy counties were gradually acquired by the Burgundian duke Philip the Good, in 1477, King Louis XI of France led an army and occupied key towns in Picardy. By the end of 1477, Louis would control all of Picardy, in the 16th century, the government of Picardy was created. This became a new region of France, separate from what was historically defined as Picardy. The new Picardy included the Somme département, the half of the Aisne département. In 1557, Picardy was invaded by Habsburg forces under the command of Emmanuel Philibert, after a seventeen-day siege, St. Quentin would be ransacked, while Noyon would be burned by the Habsburg army. In the 17th century, a disease similar to English sweat originated from the region. It was called Suette des picards or Picardy sweat, the sugar industry has continued to play a prominent role in the economy of the region. One of the most significant historical events to occur in Picardy was the series of battles fought along the Somme during World War I. From September 1914 to August 1918, four major battles, including the Battle of the Somme, were fought by British, French, and German forces in the fields of Northern Picardy. In 2009, the Regional Committee for local government reform proposed to reduce the number of French regions, Picardy would have disappeared, and each department would have joined a nearby region. The Oise would have incorporated in the Île-de-France, the Somme would have been incorporated in the Nord-Pas-de-Calais

River mouth
–
A river mouth is the part of a river where the river flows into a larger river, a lake, a reservoir or an ocean. The water from a river can enter the body in a variety of different ways. The motion of the river mainly depends on the density of the river compared to the receiving water and any ambient motion in the receiving water. If the river water is denser than the surface of the receiving water, the river water will then either form an underflow or an interflow within the lake. Alongside these advective transports, inflowing water will also diffuse, at the mouth of a river, the change in flow condition can cause the river to drop any sediment it is carrying. This sediment deposition can generate a variety of landforms, such as deltas, sand bars, spits, many places in England take their names from their positions at the mouths of rivers, for example Plymouth, Sidmouth and Great Yarmouth.

English Channel
–
The English Channel, also called simply the Channel, is the body of water that separates southern England from northern France, and links the southern part of the North Sea to the Atlantic Ocean. It is about 560 km long and varies in width from 240 km at its widest to 33.3 km in the Strait of Dover and it is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some 75,000 km2. The International Hydrographic Organization defines the limits of the English Channel as follows, a line joining Isle Vierge to Lands End. The southwestern limit of the North Sea, the IHO defines the southwestern limit of the North Sea as a line joining the Walde Lighthouse and Leathercoat Point. The Walde Lighthouse is 6 km east of Calais, and Leathercoat Point is at the end of St Margarets Bay. The Strait of Dover, at the Channels eastern end, is its narrowest point and it is relatively shallow, with an average depth of about 120 m at its widest part, reducing to a depth of about 45 m between Dover and Calais. Eastwards from there the adjoining North Sea reduces to about 26 m in the Broad Fourteens where it lies over the watershed of the land bridge between East Anglia and the Low Countries. It reaches a depth of 180 m in the submerged valley of Hurds Deep,48 km west-northwest of Guernsey. The eastern region along the French coast between Cherbourg and the mouth of the Seine river at Le Havre is frequently referred to as the Bay of the Seine. There are several islands in the Channel, the most notable being the Isle of Wight off the English coast. The coastline, particularly on the French shore, is indented, several small islands close to the coastline, including Chausey. The Cotentin Peninsula in France juts out into the Channel, whilst on the English side there is a parallel channel known as the Solent between the Isle of Wight and the mainland. The Celtic Sea is to the west of the Channel, the time difference of about six hours between high water at the eastern and western limits of the Channel is indicative of the tidal range being amplified further by resonance. It was never defined as a border and the names were more or less descriptive. It was not considered as the property of a nation, strangely, before the development of the modern nations, British scholars very often referred to it as Gaulish and the French one as British or English. The name English Channel has been used since the early 18th century. In modern Dutch, however, it is known as Het Kanaal, later, it has also been known as the British Channel or the British Sea having been called the Oceanus Britannicus by the 2nd-century geographer Ptolemy. The same name is used on an Italian map of about 1450, the Anglo-Saxon texts often call it Sūð-sǣ as opposed to Norð-sǣ

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

River
–
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water, small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the term river as applied to geographic features. Many names for small rivers are specific to geographic location, examples are run in parts of the United States, burn in Scotland and northeast England. Sometimes a river is defined as being larger than a creek, but not always, Rivers are part of the hydrological cycle. Potamology is the study of rivers while limnology is the study of inland waters in general. Extraterrestrial rivers of liquid hydrocarbons have recently found on Titan. Channels may indicate past rivers on other planets, specifically outflow channels on Mars and rivers are theorised to exist on planets, a river begins at a source, follows a path called a course, and ends at a mouth or mouths. The water in a river is confined to a channel. In larger rivers there is also a wider floodplain shaped by flood-waters over-topping the channel. Floodplains may be wide in relation to the size of the river channel. This distinction between river channel and floodplain can be blurred, especially in areas where the floodplain of a river channel can become greatly developed by housing. Rivers can flow down mountains, through valleys or along plains, the term upriver refers to the direction towards the source of the river, i. e. against the direction of flow. Likewise, the term describes the direction towards the mouth of the river. The term left bank refers to the bank in the direction of flow. The river channel typically contains a stream of water, but some rivers flow as several interconnecting streams of water. Extensive braided rivers are now found in only a few regions worldwide and they also occur on peneplains and some of the larger river deltas. Anastamosing rivers are similar to braided rivers and are quite rare

Departments of France
–
In the administrative divisions of France, the department is one of the three levels of government below the national level, between the administrative regions and the commune. There are 96 departments in metropolitan France and 5 overseas departments, each department is administered by an elected body called a departmental council. From 1800 to April 2015, they were called general councils, the departments were created in 1791 as a rational replacement of Ancien Régime provinces with a view to strengthen national unity, the title department is used to mean a part of a larger whole. Almost all of them were named after geographical features rather than after historical or cultural territories which could have their own loyalties. The earliest known suggestion of it is from 1764 in the writings of dArgenson and they have inspired similar divisions in many countries, some of them former French colonies. Most French departments are assigned a number, the Official Geographical Code. Some overseas departments have a three-digit number, the number is used, for example, in the postal code, and was until recently used for all vehicle registration plates. For example, inhabitants of Loiret might refer to their department as the 45 and this reform project has since been abandoned. The first French territorial departments were proposed in 1665 by Marc-René dArgenson to serve as administrative areas purely for the Ponts et Chaussées infrastructure administration, before the French Revolution, France gained territory gradually through the annexation of a mosaic of independent entities. By the close of the Ancien Régime, it was organised into provinces, during the period of the Revolution, these were dissolved, partly in order to weaken old loyalties. Their boundaries served two purposes, Boundaries were chosen to break up Frances historical regions in an attempt to erase cultural differences, Boundaries were set so that every settlement in the country was within a days ride of the capital of the department. This was a security measure, intended to keep the national territory under close control. This measure was directly inspired by the Great Terror, during which the government had lost control of rural areas far from any centre of government. The old nomenclature was carefully avoided in naming the new departments, most were named after an areas principal river or other physical features. Even Paris was in the department of Seine, the number of departments, initially 83, was increased to 130 by 1809 with the territorial gains of the Republic and of the First French Empire. Following Napoleons defeats in 1814-1815, the Congress of Vienna returned France to its pre-war size, in 1860, France acquired the County of Nice and Savoy, which led to the creation of three new departments. Two were added from the new Savoyard territory, while the department of Alpes-Maritimes was created from Nice, the 89 departments were given numbers based on their alphabetical order. The department of Bas-Rhin and parts of Meurthe, Moselle, Vosges and Haut-Rhin were ceded to the German Empire in 1871, following Frances defeat in the Franco-Prussian War

Pas-de-Calais
–
Pas-de-Calais is a department in northern France. Its name is used in French to refer to the Strait of Dover, which it borders. Inhabited since prehistoric times, the Pas-de-Calais region was populated in turn by the Celtic Belgae, the Romans, the Germanic Franks and this linguistic border is still evident today in the toponyms and patronyms of the region. Beginning in the century, the linguistic border began a steady move to north and the east. Pas-de-Calais is one of the original 83 departments created during the French Revolution on 4 March 1790 and it was created from parts of the former provinces of Calaisis, formerly English, Boulonnais, Ponthieu and Artois, this last formerly part of the Spanish Netherlands. Some of the costliest battles of World War I were fought in the region, the Canadian National Vimy Memorial, eight kilometres from Arras, commemorates the Battle of Vimy Ridge and is Canadas most important memorial in Europe to its fallen soldiers. Pas-de-Calais is in the current region of Hauts-de-France and is surrounded by the departments of Nord and Somme, the English Channel, and it shares a nominal border with the English county of Kent halfway through the Channel Tunnel. Its principal towns are, on the coast, Calais, Boulogne-sur-Mer and Étaples, and in Artois, Lens, Liévin, Arras, however, since World War II, the economy has become more diversified. The inhabitants of the department are called Pas-de-Calaisiens, Pas-de-Calais is one of the most densely populated departments of France, and yet it has no large cities. Calais has only about 80,000 inhabitants, followed closely by Arras, Boulogne-sur-Mer, Lens, the center and south of the department are more rural, but still quite heavily populated, with many villages and small towns. Although the department saw some of the heaviest fighting of World War I, however, many of the mining towns have seen dramatic decreases in population, some up to half of their population. There are currently two universities in the department

Somme (department)
–
Somme is a department of France, located in the north of the country and named after the Somme river. It is part of the Hauts-de-France region, the north central area of the Somme was the site of a series of battles during World War I. Particularly significant was the 1916 Battle of the Somme, the 1346 Battle of Crécy, a major English victory early in the Hundred Years War, also took place in this department. The Somme department is in the current region of Hauts-de-France and is surrounded by the departments of Pas-de-Calais, Nord, Aisne, Oise, in the northwest, it has a coast on the English Channel. The main rivers are the Somme and its tributaries as well as the Bresle, at the beginning of the First World War, during the Race to the Sea of September and November 1914, the Somme became the site of the Battle of Albert. The line settled around the town of Thiepval and remained there until July 1916, the Allies had originally intended the Somme to be the site of one of several simultaneous major offensives by Allied powers against the Central Powers in 1916. However, before these offensives could begin, the Germans attacked first, as this battle dragged on, the purpose of the Somme campaign shifted from striking a decisive blow against Germany to drawing German forces away from Verdun and relieving the Allied forces there. By its end the losses on the Somme had exceeded those at Verdun, while Verdun would bite deep in the national consciousness of France for generations, the Somme would have the same effect on generations of Britons. The battle is best remembered for its first day,1 July 1916, on which the British suffered 57,420 casualties, as terrible as the battle was for the British Empire troops who suffered there, it naturally affected the other nationalities as well. One German officer, General D. Swaha, famously described it as the grave of the German field army. By the end of the battle, the British had learned lessons in modern warfare while the Germans had suffered irreplaceable losses. British historian Sir James Edmonds stated, It is not too much to claim that the foundations of the victory on the Western Front were laid by the Somme offensive of 1916. The Somme experienced war twice more in the First and Second Battles of the Somme of 1918
